<h2>Understanding Scopes — The Foundation of JavaScript</h2>
<p>In the realm of programming, a scope refers to the context in which a variable is defined and can be accessed. It acts as a protective bubble around variables, ensuring they don’t collide or interfere with each other. JavaScript provides us with several types of scopes, each serving a unique purpose in shaping our code.</p>
<h2>1. Global Scope — Reaching Across the Application</h2>
<p>Variables declared outside of any function or block reside in the global scope. This means they are accessible from any part of your codebase, granting a sense of universality to your variables.</p>
